2864

Troy, MI – February 8, 2011 – Reising Ethington P.C. attorneys David Simonelli and Rick Hoffmann successfully defended two of the firm’s clients, Severstal Dearborn, Inc. and Wheeling-Nisshin, in a patent infringement suit filed by two French units of ArcelorMittal, the world’s largest steel producer. During the trial, held in the United States District Court for the District of Delaware, Simonelli and Hoffmann successfully argued that no infringement had occurred by either of their clients and that the ArcelorMittal patent is invalid. In the decision handed down January 14, 2011, the jury agreed and found the ArcelorMittal patent invalid and that no infringement had occurred. The patent involved was United States patent number 6,296,805, relating to aluminum coated boron steel.

The jury’s verdict came less than a year from the date the complaint was filed. By negotiating with the court, a third defendant represented by other counsel, and the plaintiffs, Simonelli and Hoffmann were able to quickly bring this case to trial. As a result, Reising Ethington P.C. clients Severstal Dearborn, Inc. and Wheeling-Nisshin, Inc. are now free sell their steel in a competitive marketplace.
